EASA AD 2021-0063R1
Oxygen — Steel Braided Polyurethane Flexible Hoses — Replacement
Summary
EASA Airworthiness Directive 2021-0063R1 is an updated safety directive addressing oxygen system components on Airbus A380-841, A380-842, and A380-861 aeroplanes. It mandates the replacement of certain steel braided polyurethane flexible hoses (Part Number 32209 series) used in crew and passenger oxygen distribution systems with improved hoses (Part Number 32309 series) to prevent oxygen leakage. This directive applies to all manufacturer serial numbers of the Airbus A380 models listed.
What Changed
EASA Airworthiness Directive 2021-0063R1 revises the original AD 2021-0063 by adding a previously omitted part number to the list of affected hoses in Appendix 1. The revision clarifies the scope of affected parts and reinforces the replacement requirements. No other major procedural changes were introduced beyond this addition.
Why It Matters
This directive is critical for aviation professionals because oxygen leakage in the affected hoses can reduce oxygen flow to crew and passengers during emergencies, potentially causing hypoxia and loss of consciousness. Operators and maintenance teams must ensure compliance to maintain aircraft airworthiness and passenger safety. Failure to comply could result in unsafe flight conditions and regulatory penalties.
What To Do
Operators of Airbus A380-841, A380-842, and A380-861 aeroplanes must replace all affected oxygen flexible hoses (P/N 32209 series) with serviceable hoses (P/N 32309 series) within 42 months from 19 March 2021. Additionally, installation of affected hoses is prohibited after modification or from the effective date for aircraft without affected parts. Compliance must follow Airbus Service Bulletin A380-35-8051 instructions.
